HOS, can't speak for German guns but British guns with 2 3/4 inch chambers were proofed at only a slightly higher pressure than 2 1/2 inch guns. Still way below SAAMI specs. Thus just because a British gun has 2 3/4 inch chambers does not make it suitable for American 2 3/4 inch shells. A British gun must have the "magnum" or 1200 bar proof before it is suitable for US loads.
